When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0057] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0058] The inventors discovered in their research that early identification of features / feature combinations can be achieved by configuring a specific RACH configuration for multiple features or feature combinations. That is, when a terminal initiates random access based on a specific RACH configuration, and this specific RACH configuration corresponds to a specific feature / feature combination, the network-side device can achieve early identification of the feature or feature combination by recognizing the RACH configuration selected by the terminal. The (specified) one or more features involved in this disclosure refer to one or more individual features. For example, a feature can be one of Small Data Transmission (SDT); Reduced Capability (RedCap); Radio Access Network Slicing (RAN slicing); or Coverage Enhancement (CE). A feature combination can refer to a combination of two or more of the aforementioned features.

[0059] Alternatively, the (specified) one or more features involved in this disclosure refer to one or more combinations of R17 features, such as one feature combination of SDT and CE, and another feature combination of RedCap and RAN slicing.

[0060] That is, one or more features in this disclosure can be individual R17 features or combinations of features, and this disclosure does not limit them.

[0061] It should be noted that the multiple first characteristics mentioned later in this disclosure refer to combinations of first characteristics, and the multiple second characteristics refer to combinations of second characteristics.

[0062] The information recording method provided in this disclosure will be introduced from the perspective of the terminal side first.

[0063] This disclosure provides an information recording method. Referring to FIG1, FIG1 is a flowchart of an information recording method according to an embodiment, which can be executed by a terminal. The method may include the following steps: in step 101, recording relevant information of the Random Access Channel (RACH) configuration; wherein the RACH configuration is associated with one or more first characteristics.

[0064] In embodiments disclosed herein, the first feature includes, but is not limited to, at least one of the following: SDT; RedCap; RANslicing; CE.

[0065] Wherein, in response to one or more first features including RAN slicing; wherein, the relevant information of the RACH configuration associated with RAN slicing may include, but is not limited to, at least one of the following: feature information indicating that the feature is RAN slicing; identification information for identifying RAN slicing.

[0066] The identification information for RAN slicing can be a Network Slice AS Group (NSAG) identifier, a wireless network slice identifier, etc. The wireless network slice identifier can be Single Network Slice Selection Assistance Information (S-NSSAI) or Network Slice Selection Assistance Information (NSSAI), and this disclosure does not limit it.

[0067] In one possible implementation, the RACH is configured as the RACH configuration used by the terminal, and one or more first features are associated with the RACH configuration used by the terminal.

[0068] In another possible implementation, the RACH configuration is a RACH configuration configured by the network-side device, and one or more first characteristics are associated with the RACH configuration configured by the network-side device.

[0069] In another possible implementation, the RACH configuration can be any RACH configuration, and one or more first characteristics are associated with any RACH configuration.

[0070] In the above embodiments, the terminal side can record relevant information about RACH configuration associated with one or more first features to assist network-side devices in optimizing RACH configuration, resulting in high availability.

[0071] In some alternative embodiments, the RACH configuration information includes, but is not limited to, at least one of the following: (1) an identifier of one or more of the first features associated with the RACH configuration; (2) a feature priority parameter; (3) a random access purpose; (4) information related to the Reference Signal Receiving Power (RSRP); (5) information related to the Physical Random Access Channel occasion (RO); (6) information related to the preamble; (7) information related to the Physical Uplink Shared Channel (PUSCH); (8) backoff indication information for indicating a backoff of the Random Access (RA) mode; (9) information for indicating the cell information that initiates RA based on the RACH configuration; (10) information related to the RA priority parameter, which is associated with one or more second features; (11) information related to the feature trigger quantity, which is associated with one or more second features; (12) a first indication information for indicating whether the feature trigger quantity has been reached; and (13) a second indication information for indicating whether the terminal has successfully accessed the network based on the RACH configuration.

[0072] In embodiments disclosed herein, the second feature may include, but is not limited to, at least one of the following: SDT; RedCap; RANslicing; CE. The second feature may be the same as the first feature, or the second feature may be independent of the first feature, that is, the second feature may be different from the first feature.

[0073] For example, the RACH configuration ultimately used by the terminal can be associated with the first feature RAN slicing, and the terminal can record relevant information about the RA priority parameters associated with the second feature RAN slicing, in which case the second feature is the same as the first feature.

[0074] For example, the RACH configuration ultimately used by the terminal can be associated with the first feature RedCap, and the terminal can record the feature triggering quantity associated with the second feature SDT.

[0075] In the above embodiments, the terminal can record relevant information about RACH configuration associated with one or more first characteristics, which can be used to assist network-side devices in optimizing RACH configuration, resulting in high availability.

[0076] Subsequently, the relevant information of the above-mentioned RACH configuration will be explained one by one; however, those skilled in the art will understand that although the relevant information of these RACH configurations is explained separately, it does not mean that the relevant information of these RACH configurations must exist separately; those skilled in the art will understand that the relevant information of the aforementioned (1) to (13) RACH configurations can be combined together in any way.

[0077] (1) In some alternative embodiments, the relevant information of the RACH configuration includes the identifier of one or more of the first features associated with the RACH configuration.

[0078] In one possible implementation, the first feature includes, but is not limited to, at least one of the following: SDT; RedCap; RAN slicing; CE.

[0079] The relevant information of the RACH configuration associated with the RAN slicing includes at least one of the following: characteristic information indicating that the characteristic is RAN slicing; and identification information for identifying RAN slicing.

[0080] The identification information for RAN slicing can be an NSAG identifier, a wireless network slice identifier, etc. The wireless network slice identifier can be S-NSSAI or NSSAI. Of course, these are just examples, and this disclosure does not impose any limitations.

[0081] In one possible implementation, one or more of the first features may be associated with the RACH configuration used by the terminal, or one or more of the first features may be associated with the RACH configuration configured by the network-side device, or one or more of the first features may be associated with any RACH configuration, which is not limited in this disclosure.

[0082] (2) In some optional embodiments, the RACH configuration information includes feature priority parameters.

[0083] It should be noted that, regarding the feature priority parameters, the terminal may record the feature priority parameters of one or more features included in the first feature, or it may record the feature priority parameters configured by the network-side device, or it may record the feature priority parameters of one or more features that trigger RA. This disclosure does not limit this.

[0084] (3) In some alternative embodiments, the relevant information of the RACH configuration includes raPurpose.

[0085] In one possible implementation, raPurpose can be a RACH partition.

[0086] In another possible implementation, raPurpose can be one or more of the first features associated with the RACH configuration.

[0087] The first characteristic includes, but is not limited to, at least one of the following: SDT; RedCap; RAN slicing; CE. The limitations of the first characteristic can be found in the descriptions of other parts of the embodiments of this disclosure, and will not be repeated here.

[0088] (4) In some alternative embodiments, the RACH configuration information includes RSRP information.

[0089] In one possible implementation, the information related to RSRP includes, but is not limited to, at least one of the following: an RSRP measurement value; third indication information for indicating whether the RSRP measurement value exceeds an RSRP threshold; wherein the RSRP threshold is associated with one or more second characteristics.

[0090] In one possible implementation, the second characteristic may be the same as the first characteristic, or the second characteristic may be independent of the first characteristic, that is, the second characteristic may be different from the first characteristic. This disclosure does not limit this.

[0091] In this embodiment of the disclosure, the RSRP measurement value can be an RSRP measurement value used to determine whether the RSRP threshold is exceeded, or the RSRP measurement value can be an RSRP measurement value that triggers the recording of the relevant information, and this disclosure does not limit it in this way.

[0092] In one possible implementation, the third indication information can be indicated based on each RA attempt. Each RA process includes multiple RA attempts.

[0093] In another possible implementation, the third indication information can be indicated based on each RA procedure. Each RA procedure includes multiple RA attempts.

[0094] In this embodiment of the disclosure, the RSRP threshold includes, but is not limited to, at least one of the following: RACH configuration selection threshold corresponding to one or more of the second features; feature triggering threshold corresponding to one or more of the second features; RA mode selection threshold corresponding to one or more of the second features; Synchronization Signal Block (SSB) selection threshold corresponding to one or more of the second features; and carrier selection threshold corresponding to one or more of the second features.

[0095] Wherein, the RACH configuration selection threshold corresponding to one or more of the second features can be a selection threshold for RACH configuration associated with one or more of the second features; the selection threshold is used to enable the terminal device to determine the RACH configuration corresponding to the second feature of the RACH corresponding to the RSRP measurement value based on the RSRP measurement value.

[0096] For example, the RACH configuration selection threshold is represented as rsrp-ThresholdMsg3 (e.g., rsrp-ThresholdMsg3-r17). When the RSRP measurement value exceeds this RACH configuration selection threshold, the terminal adopts the RACH configuration associated with the CE. The trigger threshold corresponding to one or more of the second characteristics can be an RSRP threshold corresponding to one or more of the second characteristics and used to determine whether the second characteristic is triggered.

[0097] For example, the trigger threshold corresponding to SDT is represented as sdt-RSRP-Threshold. When the received signal strength on the terminal side exceeds sdt-RSRP-Threshold, the SDT procedure can be triggered.

[0098] The RA mode selection threshold corresponding to one or more of the second features can be a selection threshold for two-step RA and four-step RA corresponding to one or more of the second features; the selection threshold is used to enable the terminal device to determine the RACH configuration of two-step RA or four-step RA corresponding to the RSRP measurement value based on the RSRP measurement value.

[0099] For example, the RA mode selection threshold can be expressed as msgA-RSRP-Threshold (e.g., msgA-RSRP-Threshold-r17). The terminal selects the two-step RA mode when the RSRP measurement exceeds this threshold; otherwise, it selects the four-step RA mode. Conversely, the RA mode selection threshold can also be expressed in other forms, where the terminal selects the four-step RA mode when the RSRP measurement exceeds the threshold, and otherwise selects the two-step RA mode.

[0100] The SSB selection threshold corresponding to one or more of the second characteristics can be: the threshold for selecting the SSB corresponding to one or more of the second characteristics.

[0101] For example, the SSB selection threshold is represented as rsrp-ThresholdSSB (e.g., rsrp-ThresholdSSB-r17). When the RSRP measurement value exceeds this SSB selection threshold, the terminal selects the corresponding SSB.

[0102] For example, the SSB selection threshold is represented as cg-SDT-RSRP-ThresholdSSB. For CG (ConfiguredGrant)-SDT, the terminal selects the corresponding SSB when the RSRP measurement value exceeds the SSB selection threshold.

[0103] The carrier selection threshold corresponding to one or more of the second characteristics can refer to the threshold for selecting one or more carriers corresponding to the second characteristics.

[0104] For example, the carrier selection threshold is expressed as rsrp-ThresholdSSB-SUL. When the RSRP measurement value exceeds this carrier selection threshold, the terminal selects the supplementary uplink (SUL) carrier.

[0105] (5) In some alternative embodiments, the RACH configuration information includes RO information.

[0106] In one possible implementation, the relevant information for RO includes frequency domain resource information used by the terminal.

[0107] In another possible implementation, the RO-related information includes, but is not limited to, at least one of the following: Bandwidth Part (BWP) information; Sub-Carrier Space (SCS) information; Frequency Start information; Frequency Division Multiplexing (FDM) information; and RO resource information shared by the RACH configuration with other RACH configurations.

[0108] Among them, BWP information, SCS information, frequency start information, and FDM information are all frequency domain resource information used by the terminal.

[0109] Additionally, other RACH configurations can be RACH configurations associated with one or more other features (that are different from the first feature). Alternatively, other RACH configurations can be legacy RACH configurations. Legacy RACH configurations refer to RACH configurations that already exist in the related art and are not associated with any particular feature.

[0110] (6) In some alternative embodiments, the RACH configuration information includes information related to the preamble.

[0111] In one possible implementation, the relevant information of the preamble includes, but is not limited to, at least one of the following: the number of preamble transmissions; the maximum number of preamble transmissions; and fourth indication information for indicating whether the maximum number of preamble transmissions has been exceeded.

[0112] The number of preamble transmissions can correspond to one or more of the first features. Alternatively, the number of preamble transmissions can correspond to SSB. Or, the number of preamble transmissions can correspond to group B related configuration information.

[0113] For example, the number of preamble transmissions can correspond to at least one of the following: numberOfRA-PreamblesGroupA, messagePowerOffsetGroupB, ra-SizeGroupA.

[0114] Among them, the maximum number of preamble transmissions can be the maximum number of times the terminal can support transmitting the preamble in each RA process.

[0115] The fourth indication information can be used to indicate whether the number of preamble transmissions has exceeded the maximum number of preamble transmissions.

[0116] numberOfRA-PreamblesGroupA is numberOfRA-PreamblesGroupA-r17, messagePowerOffsetGroupB is numberOfRA-PreamblesGroupA-r17, and ra-SizeGroupA is ra-SizeGroupA-r17.

[0117] (7) In some alternative embodiments, the RACH configuration information includes the PUSCH information.

[0118] In one possible implementation, the PUSCH related information includes, but is not limited to, at least one of the following: PUSCH resource information used by the terminal; PUSCH load information; and PUSCH transmission power information.

[0120] In another possible implementation, the relevant information for PUSCH may include a combination of the information described above.

[0121] For example, PUSCH-related information may include PUSCH resource information used by the terminal; PUSCH load information msg3-PUSCH-PayloadSize for message 3; PUSCH load information msgA-PUSCH-PayloadSize for message A; PUSCH transmission power information (msg3-PUSCH transmission power information) for message 3; and PUSCH transmission power information (msgA-PUSCH transmission power information) for message A.

[0122] In another possible implementation, the relevant information of PUSCH may include, but is not limited to, at least one of the following: the absolute value of the transmission power of PUSCH; the offset of the transmission power of PUSCH relative to the transmission power of the preamble.

[0123] (8) In some alternative embodiments, the relevant information configured by RACH includes fallback indication information.

[0124] In one possible implementation, the fallback indication information is used to indicate at least one of the following: the terminal falls back from a two-step RA associated with one or more of the first features to a four-step RA associated with one or more of the first features; the terminal falls back from non-contention-based random access (CFRA) to contention-based random access (CBRA) associated with one or more of the first features.

[0125] (9) In some alternative embodiments, the RACH configuration information includes cell information for indicating the cell that initiates the RA based on the RACH configuration.

[0126] In one possible implementation, the cell can be at least one of a primary cell (Pcell), a secondary cell (Scell), or a special cell (Spcell).

[0127] Spcells typically include Pcells and primary secondary cells (PScells).

[0128] (10) In some alternative embodiments, the RACH configuration information includes information about the RA priority parameter, which is associated with one or more second characteristics.

[0129] The second characteristic may be the same as or different from the first characteristic; this disclosure does not limit this.

[0130] In one possible implementation, the RA priority parameter may include, but is not limited to, at least one of the following: a list of one or more of the second characteristics; power ramping step (powerRampingStepHighPriority); scaling factor (scalingFactorBI).

[0133] The second characteristic may be the same as or different from the first characteristic; this disclosure does not limit this.

[0134] In one possible implementation, the terminal can trigger the corresponding feature when the feature trigger threshold is reached.

[0135] For example, the data volume threshold of SDT is represented as sdt-DataVolumeThreshold. When the terminal data volume reaches the data volume threshold of SDT, the SDT process is triggered.

[0136] (12) In some alternative embodiments, the relevant information configured by RACH includes first indication information for indicating whether a feature trigger amount has been reached, the feature trigger amount being associated with one or more of the second features.

[0137] The second characteristic may be the same as or different from the first characteristic; this disclosure does not limit this.

[0138] In one possible implementation, the terminal can trigger the corresponding feature when the feature trigger threshold is reached. For example, the data volume threshold of SDT is represented as sdt-DataVolumeThreshold. When the terminal's data volume reaches the data volume threshold of SDT, the SDT process can be executed.

[0139] (13) In some alternative embodiments, the RACH configuration information includes a second indication information for indicating whether the terminal has successfully accessed the network based on the RACH configuration.
